Filed Aug. 22, 1929' 2 Sheets-Sheet 2 07;]; A. Becker Patented Dec. 22, 1931 UNITED STATES PATENT OFFICE RALPH K. BECKER, OF CLEVELAND, OHIO, ASSIGNOR FORTY-FIVE ONE-HUNDREDTHS TO BERT M. KENT, F CLEVELAND. OHIO CARTON Application filed August 22, 1929. Serial No. 387,612.

This invention relates to cartons and more particularly to the provision of pouring spouts therein.

It is one of the objects of the invention to provide a carton of the usual rectangular shape that is commonly used for packing granular materials in which the pouring spout'is formed within the limits of the ordinary blank that is now used to make a carton without a pouring spout, so that the provision of the pouring spout will not require the use of any additional stock.

It is a further object of the invention to provide a carton with a pouring spout which may be formed therein in connection with the op.- eration of cutting out the blank for the carton so that no additional blanking operations are required.

It is a further object of the invention to provide a carton with a pouring spout device that is so formed that the carton may be manufactured on the equipment that is now used for the manufacture of cartons without pouring spouts and which may be sealed by the usual sealing machines and not require any special equipment.

It is a further object of the invention to provide a carton having a pouring spout that will be devoid of externally projecting parts, 0 that may be conveniently and quickly opened and that may be readily closed and positively retained in the closed position.

Other objects of the invention and the features of novelty will be apparent from the 35 following description taken in connection with the'accompanying drawings, of Which Fig. 1s a perspective view of a portion of an ordinary rectangular carton, embodying my invention, the flaps forming one of the 40 end walls, with the pouring spout therein, be- 7 ng formed in open position and before seal- Fig. 2 is a perspective view of a carton embodying my invention, with the pouring 5 spout device projecting therefrom and indicating the manner in which it is used to dispense the contents of the carton;

Fig. 8 is a section on the line 88 .of Fig. 5.

Referring to the drawings, and more particularly to Fig. 4, it will be noted that the blank, from which the carton is made, is of a substantially rectangular shape and provided with the score lines 10, 11, 12, 13, 14 and 15 which define the sides 16, 17, 18 and 19. The blank is also provided with cuts 20, 21, 22, 23, 24 and 25 which form the flaps 26, 27, 28, 29, 30, 31, 32 and 33. Along one edge of the side 16 there is a narrow flap 34 which, when the carton is assembled, isglued to the inner surface of the side 19. This forms a rectangular tube with the flaps 27, 28, 29 and 30 projecting from one end thereof and the flaps 26, 31, 32 and 33 projecting from the other end thereof.

In manufacturing the carton the end which contains the pouring spout is closed first and before the contents are put into the carton. The manner in which the flaps, which form this end of the carton, are folded is indicated in Fig. 1 from which it will be seen that the flap 33 is first folded in and then the flap 31 is folded in so that its outerend 35 will overlap the end 36 of theflap 33. (See also 7.) The flap 31 is cut out to form a tongiie 37 .and this tongue is provided with the scone lines 38 and the cuts 39 which permit the. 5 tongue to be folded into a trough-shaped spout comprising the bottom wall 40 and the sides 41. (See Fig. 2.)

After the flap 31 has been folded into overlapping relation with the flap 33, the flap 32 is folded down over the flaps 31 and 33 and, having been provided with glue or other adhesive on both of its surfaces, it will be sesecured to the flaps 31 and 33. It will be noted that the flap 32 has a U-shaped cut-out 42 which forms a tongue 43 and, when the flap 32 is folded down against the flaps 31 and 33, the tongue 43 is secured to the underside of the bottom wall 40 of the spout, thus reinforcing the latter. The flap 26 is then folded down over the flap 32 and the latter having been provided with glue or other adhesive on both sides,as previously described, the flaps 26 and 32 will. be secured together. In thus closing the end of the carton it will be understood that the operation is performed with a mandrel or forming block arranged on the inside of the carton and having an end against which the flaps 31 and 33 may be folded and, when all of the flaps are in their closed position, pressure may be applied to the outer surface of the flap 26 to cause all of the flaps to be firmly secured together.

It will be noted that the flap 26 has an opening 44 therein which, as the blank is formed, is closed by a removable section 45, the latter being an integral part of the flap 26 and made removable by forming the opening by perforated lines.

The opening 42 is of such size and shape that when the flap 32 is folded over the flaps 31 and 33 the portions of the tongue 37 which form the sides of the spout will remain free.

The carton is filled from the opposite end and the flaps 27, 28, 29 and 30 are folded and glued in the usual manner to completely close the carton.

When it is desired to remove the contents of the carton the section is torn out and, for convenience, a small opening 46 is provided at one end of the section to permit theinsertion of the thumb nail or a suitable tool.

The end 35 of the tongue, which forms the spout, is then lifted up and turned into. the position shown in Figs. 2, 5 and 8. The sides 41 of the spout engage with the longitudinal edges of the opening 44, as the spout is withdrawn, and these edges cause these sides to be folded up to form the trough-shaped spout as shown in Fig. 2. After the desired amount of the contents of the carton have been poured out the spout ma be pushed back into the carton a d the si es 4lqvil l be flattened out, as shown\in Fig. 1, by theeilgagement of their edges with the end 36 of the-flap 33 and portions ofthe sides 41 of the spout will be confined in the space between the end 36 of the flap 33 and the overlying portion of the flap 26. The construction is suchthat when the spout is pushed back into the container the final movement is somewhat like a snap, due to thepressure which the end of the flap 33 exerts on the sides 41 of the spout, so that when the spout is restored to its closed position it will be positively retained therein by one'of said flaps being formed with a foldable spout-formin section and the intermediate one of said. aps being cut out to provide openings over the lateral portions of said spout-forming section whereb said lateral portions will not be engaged. y said intermediate flap when the carton is sealed, and said spout-forming section being withdrawable through the opening formed in said outer flap by the removal of said removable section.
